When the warning at the bottom of the window changes to "This game no longer winnable" it would be nice if a _big red X_ or something would show on the screen.
Too often a player (me) will go on without realizing that he has done something to make the game unwinnable, and then it is too late to correct the error.

Hope the devs read this forum.
